an outcomes study utilizing allomend(r) hd for superior capsular reconstruction

Conditions: Rotator Cuff Tear or Rupture, Not Specified as Traumatic

Summary: rotator cuff tears can usually be repaired with excellent results, however some chronic, extensive rotator cuff tears are not reparable secondary to tendon retraction with inelasticity, muscle atrophy, and fatty infiltration. arthroscopic superior capsular reconstruction (scr) utilizing allograft or autograft tissue has been shown to restore superior glenohumeral stability and function of the shoulder joint in patients with irreparable rotator cuff tears. grafts utilized for scr have included fascia lata, hamstring autograft, human acellular dermal tissue matrix (hadtm), and acellular porcine dermal xenograft. due to donor morbidity associated with autografts and the graft rejection potential of xenograft, hadtm has become a common graft of choice for scr. the purpose of this study is to determine if patients treated with scr using allomend have acceptable clinical and anatomic outcomes.
